Wasn't trying to force the tp2 to gsm just wondering if I could take the SIM and use it on a gsm only phone.

Switching to GSM is not easy, it would require them to put up new GSM towers and get all new phones. They would never go through that much hassle just so there customers could use any phone from any service provider, they would not like people to be able to do this. Since Sprint is a CDMA service provider, that is why you can't use GSM phones. Sprint only put this GSM feature on certain phones, so you could use the phone in other countries, but just because it has the feature of a SIM slot on this phone, Sprint is still CDMA and use's ESN's to identify their phones. By switching the SIM card, the Touch Pro 2 would still be activated on your Sprint account.

I know that most phones aren't GSM/CDMA i was mainly referring to "Sprint" since I have their service. If the EVO is not a GSM/CDMA phone why does it come with a SIM card?(best of my knowledge) and on Sprint like the TP2 which is GSM/CDMA? I know that switching either from CDMA to GSM or GSM to CDMA would be very expensive. That is why TMobile is having a hard time. Either buy out Sprint or Sprint buy out TMobile. But in my opinion GSM might be the standard in the future. Eventually CDMA phones will be phased out. I think that worldwide the census is more GSM than CDMA. So how can Sprint identify their phones overseas without CDMA capabilities... GSM? What i was trying to get at is if you are using an unlocked GSM phone with no way of using CDMA would you be able to use it with Sprint SIM card? How would the SIM card determine where it is, overseas? Cant check CDMA because of no capabilities on a GSM only phone, would identify itself as being overseas ...GSM...right?

You also said that the TP2 would still be activated on the Sprint account? Would that be the phone or phone number? How would you it determine that if you go overseas? Does the TP2 "deactivate itself" and activates the SIM card? or is it just the number that gets transferred to SIM?

So really the ESN doesnt really matter on a GSM network? Because the GSM network doesnt have the ability to read CDMA? So this answers my question about having a GSM only phone with a Sprint SIM card, IF and only if the answer is yes?

Not necessarily talking about the TP2 just on GSM only phones.
